System Providing Mote Network Emulation of One or More Legacy SensorDevices

FIG. 1 is a block diagram of an embodiment of a system providing motenetwork emulation of one or more legacy sensor devices.

A mote network within a volume/area 117 includes multiple motesensor/processors. For purposes of illustration, three motes 102, 103,and 104 are shown, although in practice the network could have more orfewer (typically more) motes. Mote 103 is shown in more detail, having acommunication interface 106, an environmental sensor 107, and otherlogic 109 to carry out/participate in various acts as described herein.

The system further includes at least one external device 111 having itsown logic 113 to carry out/participate in acts described herein, and atleast one legacy device 119 adapted to interact with non-mote (a.k.a.legacy) sensors. The device 111 may include an interface 121 to interactwith the device 119 by emulating one or more non-mote sensors.

Readings may be collected from a number of mote sensors (e.g., one, two,three, etc., mote sensors) of a mote network (henceforth, “datacollection”), the mote sensors located at a number of mote sensorlocations. A number of “legacy” (a.k.a. non-mote) sensors may beemulated as a source or sources of the readings (henceforth, “sensoremulation”). In systems where the location of the legacy sensors is afactor, legacy sensors may be emulated to be at particular locations.

Sensor emulation may include and/or involve emulating, as a source orsources of the readings, a number of sensors at a number of sensorlocations different than the number of mote sensors. For example, alarge room may be created by merging two rooms (e.g. removing a wall),each room having a thermocouple connecting to the heating system. Thethermocouples may be removed as part of the renovation, with the wiresto the thermocouples remaining To replace the removed thermocouples, alarge number of motes (say, 80 motes, including motes 102-104) havingtemperature sensors may be placed in locations throughout the room. Theinterface device 111 may be attached to the thermocouple wires to theheating system. Furthermore, sensor emulation may include emulation ofanother mote network; for example, a new mote sensor network mightemulate an old (e.g., failing) one.

Emulation information may be provided to the device 111 in order toenable the device 111 to emulate the removed thermocouples usingreadings from one or more motes of the mote network. One or more of themotes may communicate temperature readings to the device 111, which mayapply logic 113 to emulate the thermocouple readings using the motereadings. The device 111 may convert the mote readings to analog signalscompatible with the legacy thermocouple wires and may communicate thesesignals using the wires to the heating system.

Thus, data collection may involve collecting readings from a number ofmote sensors more or less than the number of sensors being emulated.There may be various manners of implementing data collection, includingbut not limited to collecting readings from at least one mote sensor ata location different than any of the sensor locations. A single sensormay be emulated, possibly at a single location such as location 131, ormore than one sensor of the same or different types may be emulated.(See the previous example for a collection of a large number of motesthat emulate in this case, two thermocouples).

Sensor emulation may involve improving upon an accuracy of readings thatwould be provided by the sensors. Greater accuracy may be accomplishedby collecting readings from a number of mote sensors greater than thenumber of sensors. Thus, in the previous example, emulation of twothermocouples by a large number of mote sensors may, in some situations,increase the accuracy of the temperature readings, through statisticalaveraging and other techniques, by an order of magnitude or more overwhat the sensors themselves could provide.

As a second manner of accomplishing greater accuracy, the mote sensorsmay use a different physical technique to obtain their readings thanthat of the emulated sensors. In the previous example, the thermocouplesensors which were replaced typically may not have measurement accuracyappreciably greater than 1 degree centigrade. The mote sensors may bethermistors, which use resistors to develop temperature readings, andmay be an order of magnitude or more accurate than thermocouples.

Readings may be collected from two or more mote sensors of a motenetwork in different locations. One or more readings may be derived fromthese collected readings, where the derived readings emulate readingsfrom at least one non-mote sensor in at least one non-mote sensorlocation.

Besides replacing previously used sensors with a network of motesensors, mote sensors emulating some other type of sensor can obviouslybe used in new installations which would ordinarily use the othersensor.

Network Adaptation

Various aspects of the data collection and/or emulation may be adaptedto improve accuracy and/or account for environmental factors such asmote failures (henceforth, “network adaptation”). For example, thenumber of mote sensors, the number of mote sensor locations, and/or themote sensor locations may be adapted to account for one or more motesensors that were providing readings but which have failed. Networkadaptation may be caused by external logic (e.g. logic 113) or by themote network itself (a.k.a. the mote network is “self-adapting”).

Network adaptation may include and/or involve changing at least one ofthe mote sensor locations to improve the accuracy of the emulation ofthe sensors (henceforth, “location adaptation”). Location adaptation maybe caused by external logic (e.g. logic 113) or by the mote networkitself (a.k.a. the mote network is “self-adapting”).

Network adaptation may be performed to account for changes to one ormore of the mote sensor locations, accuracy of the emulating of thenumber of sensors, performance of the emulating of the number ofsensors, or to changes in the environment of the mote network. As anexample where a changed mote position may result in network adaptation,a mote which is providing readings used in sensor emulation may bedislodged from its position, say the underside of a table, and fall tothe floor. Its readings may then be lower, as the cold generated by airconditioning in the location is most intense on the floor. The systemmay recognize directly that the location of the mote has changed, usinglocation logic, or it may recognize that the readings being given by themote are uncharacteristic of its prior position. The system may thenadapt by selecting one or more motes to replace the mote in providingreadings used in the emulation.

As an example of when reading accuracy may trigger adaptation, thesystem may examine the accuracy of readings, either automatically ortriggered by the intervention of some person or device(s). For example,a person may bring a highly accurate thermometer into the room and takereadings at the two emulated locations. If the accuracy of the motereadings is not comparable, the system may adapt which and/or how manymotes to use to provide readings.

As another example of adaptation, motes may be added to the system, orone or more motes in the system may have their locations moved. Thesystem may then adapt the selection of motes to use for emulation,resulting in increased emulation accuracy going forward.

As another example of adaptation, a part of the mote environment becomescontaminated. For example, workers might respond to a small fire byspraying part of a wall or other surface with fire retardant, which maythen coat the motes attached thereon. The system may recognize thesemotes are no longer giving characteristic readings and may then selectone or more replacement motes.

Network adaptation may involve observing behavior and/or characteristicsof the sensors to emulate, and refining a selection of the mote sensors,the number of mote sensors, the mote sensor locations, and/or the numberof mote sensor locations in order to improve emulation of behaviorand/or characteristics of the sensors. For example, motes 102-104 mayprovide pressure readings in a pipe 117 carrying a moving fluid. Aconventional non-mote pressure sensor may also be present in the pipe.The system may observe behavior and/or characteristics of the pressuresensor to emulate, and refine a selection of the mote sensors, thenumber of mote sensors, the mote sensor locations, and/or the number ofmote sensor locations in order to improve emulation of behavior and/orcharacteristics of the non-mote pressure sensor.

Network adaptation may involve selecting one or more replacement motesensors (a.k.a. “mote replacement”) to replace one or more failed motesensors as a source of the collected readings. Mote replacement may insome cases involve the mote network selecting one or more replacementmote sensors to replace one or more failed mote sensors as a source ofthe collected readings. In other cases, external logic such as logic 113may select mote replacements.

Emulation Interface

An interface device such as device 111 may be provided to receive and/orcollect readings from the mote sensors, and to convert the readings intoat least one non-mote sensor reading. The device 111 may include logicto communicate the at least one non-mote sensor reading via a non-motesensor interface. Thus, the device 111 may serve to emulate at least onenon-mote (e.g. legacy) sensor via a mote network (henceforth, “sensorinterface emulation”). Sensor interface emulation may include and/orinvolve logic to emulate a manner of communication of the at least onenon-mote sensor. In other words, the device 111 may appear as thenon-mote sensor(s) to controllers or other devices adapted to interactwith the non-mote sensor(s).

Some applications may not employ an external device 111. Instead, themote network itself may provide the functions of the external device111.

In some applications the location(s) of the emulated non-mote sensor(s)may be relevant to controllers or other devices that interact with thenon-mote sensors. The device 111 may include and/or involve logic toapply location information for the mote sensors that provide thereadings in order to derive at least one emulated non-mote sensorlocation. For example, in the example of motes emulating thermocouples,the device 111 may determine two locations with which to associate theemulated thermocouple readings, based upon the locations of the moteschosen to provide readings for the emulation. In some situations themote network itself may provide these features.

The device 111 may include and/or involve logic to select at least onemote sensor to provide the readings (henceforth, “mote sensorselection”). Mote sensor selection may involve logic to select one ormore mote sensors to compensate for at least one failed mote sensor, andor logic to select at least one mote sensor to increase an accuracy ofemulation of the at least one non-mote sensor. In some implementations,the mote network itself may provide these features.

The device 111 may include and/or involve logic to cause a change in atleast one location from which the readings are provided. The logic tocause a change in at least one location from which the readings areprovided (henceforth, ‘mote location selection’) may include and/orinvolve logic to deselect at least one mote as a source of the readingsand to select at least one other mote as the source of the readings.This may include and/or involve logic to cause at least one mote that isa source of the readings to change position.

Process of Mote Network Sensor Emulation

FIG. 2 is an action flow diagram of an embodiment of a process of motenetwork sensor emulation. The motes in the network communicate withtheir nearest neighbors. The mote closest to the interface device passesall such communication it receives to the mote interface.

At 202 mote 1 communicates its sensor reading to mote 2. At 204 mote 2communicates its sensor reading to mote 3. At 206 mote 2 communicatesmote 1's sensor data to mote 3. At 208, 210, and 212 mote 3 communicatesthe data for itself, mote 1, and mote 2 respectively to the moteinterface.

The mote interface then calculates the derived data value for the sensoror sensors which are being emulated. At 214, this derived data iscommunicated to the controller.

The mote interface has recognized that the emulation(s) may better beperformed by making some change affecting mote 2, and at 216, the moteinterface sends the information to perform the mote 2 adaptation to mote3. At 218, mote 3 communicates this information about the mote 2adaptation to mote 2.

Mote Network Sensor Emulation

FIG. 3 is a flow chart of an embodiment of mote network sensoremulation. At 302, readings from the motes participating in the sensoremulation are obtained. At 306, the emulation is performed. At 308, theresults of the emulation are examined. At 310, if the results aresatisfactory, at 314 the emulation is complete.

If unsatisfactory, at 312 the calculations and/or motes used may beadjusted. Additional mote readings may be obtained at 302, and theprocess repeats.
